Answer:
Step-by-step explanation:
opens down refers to the value of a being negative or positive. If it opens down, then a is negative.
shifting left or right refers to the value of h
shifting up or down refers to the value of k
For the first one: y = -a (x+8)² + k
second one: y = -a(x+h)² + 7
Answer:
C.
Step-by-step explanation:
The output will be -2.
Output, generally, refers to the 'y' coordinate when the input is 'x'.
B.
This is because when you substitute y-2 in for x, you get y=(y-2)+2.
Then the twos would cancel out, leaving you with y=y which would make an infinite number of solutions for y.
x/3 = 5
If you multiply both sides by 3, you get
x = 15
